Over the next few months, the Laymans, specifically Monica and her son Josh, fucked like rabbits. Monica took her son in her bed, his bed, the kitchen, the living room, the garage, on top of the washing machine and even in her daughter Serena's bedroom.
He would cum in her, filling her cunt with cum, on her ass and thighs, all over her face and on her back making her resemble a toaster strudel. His mom was the creampie queen but enjoyed the variety. She also taught her son how to eat her out right. Her rule was that before Josh could hit, he had to give her an orgasm and then immediately afterwards he would have to give her another. For every one orgasm her son had, she got two. It wasn't long before he became a master at licking clit. Usually after mommy got done using his dick, she'd make dinner for them and then afterwards he would clean up the kitchen like a good son. After, they'd hop into bed where they'd cuddle and then fornicate again once he regained his strength. Sometimes she'd put her panties on right after her son jizzed in her. Wearing the cum soaked panties while she worked as a token of their love for each other.
Eventually, however, a problem arose. Her daughter Serena broke up with her boyfriend in November and would be spending Christmas and the rest of winter break at home. What were they to do? They could try to hide their love, but the sound was often too loud, Monica had a sensitive pussy and had a hard time controlling the volume of her moans. They could do it in the car, but car sex was cramped as they found out after the first (and last) time they attempted it. A hotel room would be too expensive and it's not like they could afford to rent one every time they he got horny or she got in the mood. She got wet easily and sometimes in the morning she'd just be innocently drinking her coffee and a flood would start in her panties and she'd need something inside her immediately. What were they going to do?
Then, sure enough, a plan came to her. If Serena fucked her brother, then what right would she have to judge her mom for doing the same thing? But how would she get her daughter to do that? Serena was always such a good girl and a sensible person. Monica was pretty sure she had left for college a virgin. Serena would need a little big of encouragement. Monica worked as a pharmaceutical rep, and she was a damn good one too. She was popular due to her big boobs and fat ass but was a great saleswoman too. At her job she often was offered test drugs so that she could familiarize herself with them. It just so happened that a new experimental drug, coined "female Viagra" was being shopped around to different doctors and she got not one, but two bottles of it! All she needed to do was slip the Viagra into her daughter's coffee and forbid her from leaving home. Eventually she'd get so horny that she'd have no choice but to fuck her brother!
In December of 2020, Serena came home. Michigan was a lot colder than Arizona and she did not miss it. Still, she was happy to see everyone and gave her mom and brother a great big hug upon seeing them again. Now that her boyfriend had broken up with her, she had started to feel sad, and her family was just the pick me up she needed. She didn't want to be alone right now.
Every morning Monica would make coffee and Serena, being the Starbucks addict she is, would drink it. Little did Serena know that her mother was slipping women's Viagra in it. Then in the evening, Monica would slip her another pill in her lemonade or wine. The Laymans were part Italian, so a glass of wine with dinner was not unusual. The pills would dissolve somewhat but this didn't seem to harm their potency too much. It wasn't long before Monica could hear her daughter playing with herself through the walls. Monica's daughter was a good little liberal who was taking the pandemic very seriously, so she didn't have to worry about her daughter sneaking off for some dick.
After a week, one night she waited until she heard the sound of moaning coming from her daughter's bedroom. This is my chance. She thought. Monica walked into the room without knocking while her daughter was laid back in her bed with one hand on her breast and the other hand under the covers. She then quickly noticed her mom in the room and jerked her head forward from its laid-back position, removed her hand from her shirt and pulled the covers up.
"I really wish you wouldn't do that."
She walked in and sat on the bed while her daughter covered herself up with the blanket to protect her modesty.
"Its just not proper for a young lady like yourself to be playing with your private parts like that. Have some respect for yourself."
"What? Why not, it's natural!"
"No, its not. God created men so that they'd fulfill these urges for us. You should wait for marriage though before you have sex. Because that'd be premarital sex obviously, well with one exception of course."
"An exception? What's that?"
"Well, you can't get married to your family, not legally anyway. So if you have sex with them it's not premarital sex, so its ok. Think of it as kind of a loophole that god created. Family members like brothers and sisters have been going at it for millennia! I even fucked my own brother once or twice when I was your age." Monica lied.
The seeds had been planted, hopefully now all she had to do was wait. In the meantime, she made sure to keep putting Viagra in her daughter's drinks. Not long afterwards, Serena's will broke. She spent night after night in heat with no release. She was horny as hell and needed someone to hold her tits and slap her ass. She just needed to be fucked. Even her bed post was starting to look good. So she found herself at her brother's bedroom door.
"Hey bro..."
"Hey, umm you realize it's like really late right??"
"Yes, but... I have a problem. You see we've been locked up for so long and I- and I could just really use a man's touch right now."
"A man's touch? But I'm your brother! Can't you just go jerk off or something!"
"I tried but it just didn't feel right. Mom said its ok if siblings get it on! Please Josh, we're in the middle of a pandemic!"
"Ok... alright I guess."
"Yay! You're the best brother ever!" She said jumping up and down, her boobs bouncing freely before she gave her brother a big hug, his face squished near her bosom.
She pulled down his basketball shorts and saw a big soft snake sleeping beneath his underwear. She pulled those down too and put his soft penis in her mouth until it inflated to over six and 3/4 inches long.
"Holy shit it's huge!" Serena exclaimed, "I've never seen one this big before!"
"Thanks."
"Oh sorry, I should probably take my pants off too!"
There was an air of awkwardness, but once they were both bottomless things got more amicable. She dropped her nighttime shorts and quickly dropped her hipster style panties. She was a lot more modest than her mom. Serena kept her shirt on at first, to make it more about getting off and getting rid of these uncontrollable sexual urges. She felt really guilty and wanted the sex to be as sterile as possible... at first.
"So... who should be on top?" She said, blushing.
"Umm should I eat you out first?"
"Trust me, that won't be necessary." Serena said, feeling so wet she worried it might drizzle onto her brother's bed.
"Ok let's do missionary then." Josh said as he got on his knees while Serena laid on the bed and spread her legs apart.
"Wait, do you have a condom?"
"Umm yeah," Josh said opening up his nightstand and grabbing one that had expired years ago.
Josh inserted his long condom covered penis into her flooded cunt and started to thrust. The brother and sister said nothing at first and just looked each other in the eyes until eventually Serena looked away. As the sex continued eventually the two got more comfortable. Serena eventually started to moan in pleasure. Josh also noticed that there was no blood on his dick. Guess my sister isn't a virgin, he thought. Eventually, his sister's pussy was just so tight that he couldn't help but comment.
"Damn sis. If I had known your shit was this tight, I would have fucked you a long time ago."
Eventually Josh's controlled and respectful strokes lost their rhythm and turned into hard thrusts into his sister's tight pussy. The added force made it harder for Serena to keep her quiet as she started to be more vocal, unable to help herself.
"Fuck me! Fuck me!" Serena moaned as her mom burst through the door.
"What are you doing?!" Monica screamed.
